What does TypeError string indices must be integers mean?
All the characters of a string have a unique index . This index specifies the position of each character of the string. TypeError: string indices must be integers means an attempt to access a location within a string using an index that is not an integer.

What does TypeError list indices must be integers or slices not str mean?
These indexes are always defined using integers. You might declare a variable that has the index value of a list element. But if this variable does not have an integer value and instead has a string value, you will face an error called “TypeError: list indices must be integers or slices, not str”.
Can string indices be floats?
All the characters of a string have a unique index. This index specifies the position of each character of the string. But you have to remember that all the indexes are integers. When you specify a string or a float as the index, you will encounter an error called TypeError: String Indices Must be Integers.
How do you convert a string to an integer in Python?
To convert a string to integer in Python, use the int() function. This function takes two parameters: the initial string and the optional base to represent the data. Use the syntax print(int(“STR”)) to return the str as an int , or integer.
How do you fix a string index out of range in Python?
The “TypeError: string index out of range” error is raised when you try to access an item at an index position that does not exist. You solve this error by making sure that your code treats strings as if they are indexed from the position 0.
What is a string indice?

Why is my string index out of range?
The string index out of range means that the index you are trying to access does not exist. In a string, that means you’re trying to get a character from the string at a given point. If that given point does not exist , then you will be trying to get a character that is not inside of the string.
How do I stop list indexing out of range?
“List index out of range” error occurs in Python when we try to access an undefined element from the list. The only way to avoid this error is to mention the indexes of list elements properly.
